This is a simple sun glow effect. It uses a cloud layer that fills up a ton of space. You won't even notice that it's there apart from the glow around the sun and any other light sources you may have and a slight blur on the background sphere. The density fractal is contained within the cloud layer node. All you have to do is put the node at the top (or bottom, or anywhere else you want
) of your atmo stack. This node is unnecessary in scenes where the camera is within the atmosphere, as the atmosphere already creates the glow. It works best in situations where there is no air, i.e., on the moon or in space. Enjoy!
